[Sensor head] Mounting

The light emitting and receiving surfaces of the sensor head must be free of water, oil, fingerprints, and other substances that refract light as well as dust, grit, and other objects that intercept light.
Do not allow ambient light such as sunlight to directly hit the light receiving section of the sensor head. In particular, if precision is required, use this product by mounting a douser (or similar material) on the sensor head.
A serial number is marked on each opposite surface of the light emitting and receiving surfaces of the sensor head. Use a pair of emitter and receiver that have the same serial number.

  • For the installation of sensor heads, use M3 screws and tighten to the torque of 0.5 N·m. M3 screws are not provided with the product.

Sensor head : Mounting

[Controller] Mounting

Mounting
1. Insert the rear of the mounting part into the DIN rail.
2. While pressing down on the rear of the mounting part, insert the front of the mounting part into the DIN rail.

Mounting

Removal method
1. Grasp the product and push forward.
2. Lift the front to remove.

Removal method

Attaching the sensor head connection cable
Mounting
1. Insert the sensor head connection cable into the connector for the sensor head connection cable on the controller.

Mounting

Removal method
1. Grasp the controller, and while pressing on the lock release lever on the connector of the sensor head connection cable, pull toward you to disconnect.
Note: If you attempt to disconnect the cable by pulling it without pressing the lock release lever, cable wire breakage and connector damage may occur.

Removal method

[Controller] Connection

Always shut off the power before connecting a slave unit to or disconnecting a slave unit from the master unit. Risk of controller damage if you attempt connection with the power on.
Insert the male connector firmly into the female connector. Risk of controller damage if not completely connected.
When connecting slave units to a master unit, connect only NPN output types, or only PNP output types.
Dissimilar output types cannot be connected together.
To connect units, the units must be mounted on a DIN rail. Attach end plates MS-DIN-E (optional) so as to enclose the connected units at the ends.

  • If the HG‑TC□ controller is used together with the HG‑SC□ controller for contact-type digital displacement sensor HG-S series, make sure to use the HG-SC□ controller manufactured in or after February, 2019.
    Furthermore, connect the slaves units of the same series to the side closer to the master unit and the slave units of the other series to the far side.

[Common] Wiring

The product is designed to fulfill the specifications when combined with the HG-T□ sensor head and HG-TC□ controller. If the product is used in combination with other products, it not only fails to meet the specifications but also generates a malfunction in some cases.
For the controller DC power supply, only use a power supply that is isolated by means of an isolation transformer or otherwise.
Risk of short-circuiting and damage to the controller or power supply if a transformer such as an auto transformer is used. Risk of short-circuiting and damage to the controller or power supply if incorrectly mounted or connected.

  • Make sure that the power supply is off while performing wiring or expansion work.
  • After you have completed wiring work, check the wiring carefully before switching on the power.
  • Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
  • Verify that the supply voltage variation is within the rating.
  • If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
  • Make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint.

[Common] Others

  • This device has been developed / produced for industrial use only.
  • Do not use this product outside the range of the specifications. Risk of an accident and product damage. There is also a risk of a noticeable reduction of service life.
  • Do not use during the initial transient time after the power supply is switched on.
  • To ensure performance, use the product at least 30 minutes (warm-up time) after the power is turned ON.
  • This product (controller and sensor head receiver) uses an EEPROM. The EEPROM has a service life of one million setting operations.
  • This product is suitable for indoor use only.
  • Avoid dust, dirt, and steam.
  • Take care that the product does not come in direct contact with organic solvents such as thinner.
  • Take care that the product does not come in direct contact with strong acid or alkaline.
  • Take care that the product does not come in direct contact with oil or grease.
  • Do not use in an environment containing inflammable or explosive gases.
  • Performance may not be satisfactory in a strong electromagnetic field.
  • The sensor head is watertight, but the connector is not dustproof, waterproofing, or corrosion-resistant due to its structural reasons, so measurements cannot be taken under the water or in the rain. Pay attention to the environment where the product is used.
  • This product is a precision device. Do not drop or otherwise subject to shock. Risk of product damage.
  • Never attempt to disassemble, repair, or modify the product.
